Chronic tendon and muscle pain can limit the activities that used to come easily, at work, during a workout, or just moving through an ordinary day. Radial shockwave therapy offers a way to help bring you back to the person you were before pain. Pain Doctors Medical, led by Dr. Ilana Etelzon, a physician double-board certified in Physical Medicine and Rehabilitation and Interventional Pain Management, uses this acoustic wave technology to help patients regain strength and mobility before surgery ever becomes part of the conversation.
With offices in Brooklyn, New York, and Clifton, Newark, and Perth Amboy, New Jersey, Pain Doctors Medical treats patients across the region seeking a non-surgical path back to movement.
How It Works
Radial shockwave therapy delivers acoustic pressure waves through a hand-held applicator pressed against the skin. A projectile inside the device accelerates toward the tip, and the resulting pressure wave spreads outward through the tissue, with its energy concentrated near the point of contact. Physiatrist Joshua Romero, M.D. of Mayo Clinic, explains that this mechanical stimulus triggers cellular changes that prompt cell migration, new blood vessel growth, and shifts along pain pathways. In plain terms, the treatment nudges the body’s own repair systems into gear.
This is different from a general massage or a topical treatment. Radial shockwave therapy reaches deeper structures where scar tissue, calcification, and chronically tight trigger points tend to live, and it does so without needles or incisions.
Common Conditions Treated
Radial shockwave therapy is best suited for tendon and soft tissue conditions, including:
- Tendinopathy of the elbow, shoulder, knee, or Achilles
- Plantar fasciitis
- Calcific deposits in tendons
- Bursitis
- Myofascial pain syndrome and muscle trigger points
- Scar tissue restricting mobility after an injury
A randomized controlled trial published in the Journal of Clinical Medicine found that patients with acute low back pain who received radial shockwave therapy alongside physical therapy reported meaningful pain improvement compared with those who received a placebo. That kind of evidence is part of why the therapy has become a standard tool for physiatrists treating musculoskeletal pain.
What to Expect During Treatment
A typical radial shockwave session at Pain Doctors Medical takes about 10 to 20 minutes. Dr. Etelzon or her clinical team applies a coupling gel to the treatment area, then guides the applicator over the site of pain. Because pain is sometimes felt away from its actual source, patient feedback during the session helps pinpoint the exact area that needs treatment. Most protocols call for two sessions per week over three to four weeks, though the exact plan depends on the condition being treated.
Does Radial Shockwave Therapy Work?
Alexandra DeFrance, PA-C, a physician assistant at Pain Doctors Medical, specializing in orthopedics and regenerative medicine, has seen the therapy change the course of recovery for patients who had tried everything else. She points to a 47-year-old patient who came in after a motor vehicle accident with persistent neck and lower back pain, along with muscle spasms so severe she struggled to look over her shoulder, drive, or sleep. The patient had already completed a full course of supervised physical therapy and chiropractic care two to three times a week without lasting relief.
“Radial shockwave therapy was highly successful for her because it specifically targeted her chronic myofascial pain syndrome and active trigger points,” DeFrance said.
Her case reflects a pattern that DeFrance and Dr. Etelzon often see. Patients who have exhausted conservative care still have options that do not involve surgery.
How Long Does It Take for Radial Shockwave Therapy to Work?
Many patients notice some reduction in pain shortly after their first session, largely because the acoustic waves interrupt local pain signaling. More durable improvements in pain and function typically build over 8 to 12 weeks as tissue remodeling continues, according to Mayo Clinic’s Dr. Romero. Patience through the full course of sessions matters more than the first appointment.
How Long Do Shockwave Treatments Last?
Results depend on the condition being treated and how consistently the recommended protocol is followed. Most patients complete a series of sessions over three to four weeks, and the tissue changes triggered during that window continue to develop for weeks afterward. For chronic tendon conditions, many patients maintain their improvement well beyond the treatment period, particularly when shockwave therapy is paired with a supportive physical therapy or strengthening program.
How Painful Is Shockwave Therapy?
Most patients describe the sensation as a deep, dull ache rather than sharp pain, and it is generally well tolerated without anesthesia. Some discomfort at the treatment site is expected. It confirms the waves are reaching the correct tissue. Intensity can be adjusted during the session based on patient feedback, and most people return to light daily activity the same day.
What Are the Negative Side Effects of Shockwave Therapy?
Radial shockwave therapy carries a favorable safety profile. Documented side effects include mild skin redness, bruising, swelling, or tingling at the treatment site for up to 24 hours. Less commonly, patients can experience localized hematoma, nerve irritation, or temporary soreness. The treatment is not recommended for patients who are pregnant or who have a malignant tumor, severe coagulopathy, or certain bone or nerve conditions in the treatment area, which is why a full evaluation with Dr. Etelzon precedes any treatment plan.
What Not to Do After Shockwave Therapy?
Patients are generally advised to avoid intense exercise, heavy lifting, or activities that stress the treated area for a day or two after each session. Nonsteroidal anti-inflammatory medications are typically discouraged in the days surrounding treatment, since inflammation is part of how the therapy stimulates tissue repair. Ice should only be used if a provider recommends it, as it can counteract the healing response the treatment is designed to trigger. Following the specific aftercare plan from Dr. Etelzon’s team gives the tissue the best chance to remodel properly between sessions.
How Much Does Radial Shockwave Therapy Cost?
Cost varies based on the number of sessions recommended and the condition being treated. Radial shockwave therapy is not covered by most insurance plans for many conditions, so Pain Doctors Medical works directly with patients to develop a treatment plan and offers flexible payment options. The best way to get an accurate estimate is a consultation, where Dr. Etelzon can evaluate the condition and outline exactly what a course of treatment would involve.
For patients who have tried physical therapy, medication, and rest without lasting relief, radial shockwave therapy offers a next step that does not require surgery or a long recovery. Scheduling a consultation with Dr. Etelzon is the first step toward finding the right treatment plan.
